Chicago is home to one of the most diverse economies in North America — world-class healthcare systems on the Magnificent Mile, a booming fintech corridor, major law firms, manufacturing conglomerates, and a rapidly expanding technology sector. This diversity makes the city an attractive target for cybercriminals who know that Chicago organizations hold enormous quantities of sensitive data: patient health records, legal strategy documents, proprietary trading algorithms, and consumer financial information.\n\nZerosums Technology delivers cybersecurity programs built for the complexity of Chicago's business environment. Our security engineers combine deep technical expertise with a thorough understanding of the regulatory landscape facing Illinois organizations — including HIPAA, the Illinois Personal Information Protection Act (PIPA), GLBA, and emerging state privacy frameworks. We build security programs that satisfy auditors, satisfy boards, and actually work in practice.\n\nOur Chicago engagements begin with an honest assessment of your current posture. We interview stakeholders, analyze network architecture, review identity and access controls, and evaluate endpoint configurations against CIS Benchmarks and NIST CSF. The result is a risk-ranked remediation roadmap that your IT team can execute systematically — or that Zerosums can manage on your behalf through our ongoing managed security service.\n\nFor Chicago healthcare organizations, we pay particular attention to the intersection of clinical workflow and security controls. Implementing overly restrictive access controls in a busy emergency department creates risk of a different kind. We design controls that protect PHI without impeding care delivery, drawing on our experience with Epic, Cerner, and other major EHR platforms.
